DISINFECTANT VESSEL.

SPECIFICATION forming part of Letters Patent No. 744,978, dated November24, 1903.

Application filed March 23, 1903. Serial No. 149,172. N model-l To allwhom it may concern:

Be it known that I, HEINRICH PFLIIGER, a subject of the King of Prussia,Emperor of Germany, residing at Frankfort-on-the-Main, Germany, haveinvented certain new and useful Improvements in Disinfectant Vessels, ofwhich the following is a specification.

The subject of the present invention is a closure for disinfectantvessels. The disinfectant-gases are evolved within the vessel and aresimultaneously forced outward on all sides and upward as well. This isefiected by arranging, first, several horizontal equally- .closed abovewith a cap 71.

distanced nozzles, and,secondly, an upwardlydirected nozzle in a centertube of the closure. This latter nozzle in consequence of its specialconstruction acts also as a safety-valve for the vessel.

In the accompanying drawings, in which my invention is illustrated,Figure 1 is a vertical section of the closure. Fig. 1 is a verticalsection of the closure with the tube 6 rotatably mounted; Fig. 2, a planview thereof. Fig. 2 is a plan view of the closure shown in Fig. 1; Fig.3, a detailedview of the vertical nozzle, and Fig. 4 a modified form ofhorizontal nozzle.

Ct is a portion of the air-tight disinfectant vessel,within which thedisinfectantgases are evolved by means of a fire kindled thereunder orby similar means. An opening 0 allows of the filling of the vessel withthe disinfecting material. To the flange 1), surrounding this opening,is screwed the socketpiece d, which is tapped to receive the thread edend of the vertical distributingtube 6. Into the sides of the latter arescrewed several nozzles f, four being shown in the drawings. In the topof the tube 6 is also arranged a vertical nozzle g, which in consequenceof its special arrangement serves as a safetyvalve. Into the tube 6 isscrewed a sleeve h, having at its lower end a flange is and being In thesides of this sleeve are several openings Z. Within this sleeve slidesthe vertical nozzle g, Fig. 8, having at its lower end a flange n and acollar m, between which are arranged the openings o. A spring, bearingagainst the cap i of the sleeve and the collar m of the nozzle, tends tokeep the nozzle g in the position indicated in Fig. 1.

The gases on being evolved enter the distributiug-tube e and pass out inthe directions indicated by the arrows in Fig. 1. Should the pressurewithin the vessel reach a dangerous height, the safety-valve comes intoaction. The nozzle gslides upward within. the sleeve h under theexcessive pressure within the vessel, overcoming the spring 19, untilthe openings 0 correspond with the openings Z. The gases then findopenings of considerably greater dimensions. One can also screw into thedistributingtube e bent horizontal nozzles, as shown in Fig. 4. The tube6 is not in this case rigidly secured, but is held in the socket d bymeans of suitable bearings, so as to be able to rotate. If now the gasesstream out through these bent nozzles at a certain speed, the wholedelivery apparatus is set into rotary motion, where an even greaterdiffusion of the gases is obtained.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-

1. In a closure for disinfectant vessels, a delivery-nozzle sliding in asleeve under the influence of a spring and having also lateral openingsnormally closed by said sleeve, said sleeve having openings, which underraising of the nozzle under excessive pressure coincide with the lateralopenings in the nozzle, substantially as described.

2. In a closure for disinfectant vessels, a nozzle having an opening fordelivery, a flange n and collar m, openings 0 between said flange andcollar, in combination with a spring 1) bearing against said collar m,and a sleeve h inclosing said spring and normally closing openings 0,holes Z being provided in said sleeve to coincide with openings 0 incase of the nozzle rising under excessive pressure, substantially asdescribed.

3. In a closure for disinfectant vessels, a delivery-nozzle sliding in asleeve under influence of a spring and having also lateral openings,openings in said sleeve, a tube into which said sleeve is secured, andlateral nozthe vessel, to which said socket may be sezles projectingfrom said sleeve, substantially cured, substantially as described. ro asdescribed. In testimony whereof I have hereunto set 4.
